Zoom has duplicated my recurring events since updating

I have been using zoom for a few years now and have both one off meetings and recurring appointments set up in there. I recently upgraded to a new laptop and was prompted to update the zoom client version too. My one off meetings are fine but all of my recurring meetings have been duplicated many MANY times - so I have to scroll pages and pages to get to the one I need. Anyone else? Is there a quick fix and/or if I delete one will it delete the link so it doesn't work? These are all for paying clients so I'm keen not to mess it up!!!
